will not provide immigration sponsorship for this position.\nJob Description:\nSenior Network Engineer\nDCNS - Network Triage & Troubleshooting\nThe Team\nFidelity’s Network Triage and Troubleshooting (NTT) team provides advanced technical troubleshooting and incident response for complex technology issues impacting Fidelity’s internal business operations and external customers.\nNTT engineers work across network, security, cloud, application, and infrastructure domains to rapidly isolate issues, mitigate customer impact, identify root cause, and improve the resiliency of Fidelity’s technology environment.\nThe team operates at the intersection of deep technical troubleshooting and major incident response, partnering across engineering, operations, application, cloud, security, and service-provider teams to restore service and drive complex issues through root cause and corrective action.\nPotential shift schedules\n4 10-Hour Days\nWednesday - Saturday, 10:00 AM - 8:00 PM EST OR\nSunday - Wednesday, 10:00 AM - 8:00 PM EST\nThe Expertise You Have\n5+ years of hands-on experience supporting and troubleshooting complex enterprise network and infrastructure environments.\nDeep understanding of TCP/IP, routing and switching technologies, including BGP, OSPF, VLANs, VRFs, NAT, and high-availability network designs.\nExperience troubleshooting network security technologies including firewalls, proxies, VPNs, segmentation, and DMZ architectures.\nExperience with load balancing, DNS/GSLB, application delivery, and network traffic management technologies.\nHands-on experience with AWS and/or Azure networking, connectivity, and security constructs.\nExperience using packet analysis, monitoring, and network observability platforms to diagnose complex performance and connectivity issues.\nExperience with network automation, scripting, APIs, and infrastructure-as-code practices.\nExperience working within ITSM disciplines including Incident, Problem, and Change Management.\nCisco CCNP, Check Point CCSE, AWS/Azure networking, security, or equivalent industry certifications are desirable.\nThe Skills You Bring\nAdvanced troubleshooting and analytical skills with the ability to isolate complex problems across network, security, cloud, application, and infrastructure domains.\nDeep knowledge of TCP/IP, packet flow, routing protocols, DNS, NAT, firewalls, proxies, VPNs, and load-balancing technologies.\nStrong understanding of application communication patterns, including HTTP/HTTPS, TLS, APIs, and client/server connectivity.\nExperience performing packet-level analysis using tools such as Wireshark and enterprise packet/network performance platforms.\nExperience leveraging network observability and monitoring solutions such as ThousandEyes, Splunk, Riverbed AppResponse, or comparable technologies.\nStrong understanding of AWS and/or Azure networking, including VPC/VNet architecture, routing, security controls, load balancing, and hybrid connectivity.\nKnowledge of software-defined networking and modern application architectures including containers, Kubernetes, PaaS, APIs, and cloud-native services.\nExperience with Python, Ansible, APIs, network automation, and infrastructure-as-code technologies.\nAbility to correlate telemetry from multiple platforms and develop evidence-based hypotheses to efficiently isolate problems and identify root cause.\nAbility to lead technical troubleshooting during high-severity incidents while maintaining clear communication with engineering teams, business partners, and leadership.\nStrong written and verbal communication skills with the ability to translate complex technical findings into concise, understandable business-impact statements.\nDemonstrated curiosity and a continuous-learning mindset across networking, security, cloud, automation, observability, and emerging technologies.\nThe Value You Deliver\nServe as a senior technical troubleshooter for complex, high-severity production incidents affecting Fidelity associates, applications, and external customers.\nRapidly assess incidents, establish troubleshooting strategies, isolate fault domains, and drive technical teams toward mitigation and root cause.\nAnalyze network telemetry, packet captures, logs, routing information, application flows, and infrastructure data to develop evidence-based conclusions.\nTroubleshoot across traditional data center, cloud, hybrid, security, and application environments rather than stopping at individual technology boundaries.\nPartner closely with Network Engineering, Security, Cloud, Application, Infrastructure, Operations, and external service providers during complex incidents.\nProvide technical leadership during major incidents by helping teams establish facts, challenge assumptions, prioritize troubleshooting efforts, and maintain focus on service restoration.\nIdentify recurring failure patterns and translate incident learnings into monitoring improvements, automation, documentation, and longer-term corrective actions.\nImprove troubleshooting efficiency through automation, observability, telemetry correlation, and infrastructure-as-code practices.\nClearly communicate technical findings, business impact, mitigation strategies, and root cause to both engineering teams and senior leadership.\nMentor engineers and contribute to stronger troubleshooting methodologies, technical capabilities, and operational practices across the broader organization.\nContinuously evaluate emerging technologies, including AI/ML and advanced analytics, that can improve troubleshooting, observability, automation, and operational decision-making.\nTechnical Leadership\nAs a Senior Network Engineer within NTT, you will be expected to independently lead complex troubleshooting efforts, organize and influence technical teams during high-severity incidents, challenge assumptions using data, and drive investigations from initial triage through mitigation, root cause, and corrective action.\nYou will help raise the technical capabilities of the organization through mentoring, knowledge sharing, documentation, automation, and continuous improvement of troubleshooting practices.\nWhat Success Looks Like\nSuccessful NTT engineers are naturally curious and comfortable working in situations where the source of a problem is not immediately known.\nYou may begin an investigation without knowing whether the issue resides within the network, firewall, proxy, DNS, cloud environment, load balancer, application, server, service provider, or another technology domain. You use telemetry, packet analysis, logs, monitoring data, and disciplined troubleshooting to follow the evidence, isolate the fault domain, and help teams restore service quickly.\nYou are comfortable going beyond traditional networking boundaries, learning unfamiliar technologies when necessary, and bringing the right engineering teams together to solve complex problems.\nMost importantly, you balance technical depth, urgency, collaboration, and clear communication to deliver the best possible experience for Fidelity’s customers and associates.\nFidelity’s Onsite Working Model\nFidelity is transitioning to a full-time onsite working model through a phased rollout across regions and roles. Currently, some roles and locations require 100% onsite presence, while others require less. Onsite expectations are likely to evolve as the rollout continues. This transition does not apply to fully remote roles.\nCertifications:\nCategory:\nInformation TechnologyPlease be advised that Fidelity’s business is governed by the provisions of the Securities Exchange Act of 1934, the Investment Advisers Act of 1940, the Investment Company Act of 1940, ERISA, numerous state laws governing securities, investment and retirement-related financial activities and the rules and regulations of numerous self-regulatory organizations, including FINRA, among others.
